The Thermo Scientific IonPac® CS19 carboxylate-functionalized cation-exchange column is tailored for the separation of six common cations, small polar amines (including alkanolamines and methylamines) and moderately hydrophobic and polyvalent amines (including biogenic amines and alkyl diamines) using simple aqueous eluents and elevated temperatures. The CS19 column is ideal for use with RFIC systems for automatic methanesulfonic acid eluent generation.

Features:

• For analysis of amines including alkanolamine and methylamines in diverse sample matrices


• For analysis of moderately-hydrophobic amines including biogenic amines, alkyl diamines, and polyvalent amines


• Optimized for simple acidic gradient separations with minimal baseline shift


• Ideal Reagent-Free electrolytic suppression with the Cation Self-Regenerating Suppressor CSRS® 300


• Compatible with organic solvents, acetonitrile and acetone up to 100%, excluding alcohols


• High capacity allows routine analysis of high-ionic strength samples

The IonPac CS19 cation-exchange column supports isocratic and gradient separations of polar amines, moderately hydrophobic amines, and polyvalent cations using suppressed conductivity detection. The CS19 column has a higher capacity than the CS18 column. This allows the analysis of widely disparate peak pairs and high-ionic strength matrices with less overloading of the column.
